Tom Lane	ed845c7374	Fix relcache refcount leakage when inv_drop is applied ... to a non-LO relation.	26 years ago

Tom Lane	9c95f8c9b2	Repair bugs discussed in pghackers thread of 15 May 1999: creation of a ... relcache entry no longer leaks a small amount of memory. index_endscan now releases all the memory acquired by index_beginscan, so callers of it should NOT pfree the scan descriptor anymore.	26 years ago

Bruce Momjian	97dec77fab	Rename several destroy* functions/tags to drop*.	26 years ago
Bruce Momjian	86ef36c907	New NameStr macro to convert Name to Str. No need for var.data anymore. ... Fewer calls to nameout. Better use of RelationGetRelationName.	27 years ago
Tom Lane	db3c4c3a2d	Split 'BufFile' routines out of fd.c into a new module, buffile.c. Extend ... BufFile so that it handles multi-segment temporary files transparently. This allows sorts and hashes to work with data exceeding 2Gig (or whatever the local limit on file size is). Change psort.c to use relative seeks instead of absolute seeks for backwards scanning, so that it won't fail when the data volume exceeds 2Gig.	27 years ago
Tom Lane	bd272cace6	Mega-commit to make heap_open/heap_openr/heap_close take an ... additional argument specifying the kind of lock to acquire/release (or 'NoLock' to do no lock processing). Ensure that all relations are locked with some appropriate lock level before being examined --- this ensures that relevant shared-inval messages have been processed and should prevent problems caused by concurrent VACUUM. Fix several bugs having to do with mismatched increment/decrement of relation ref count and mismatched heap_open/close (which amounts to the same thing). A bogus ref count on a relation doesn't matter much *unless* a SI Inval message happens to arrive at the wrong time, which is probably why we got away with this sloppiness for so long. Repair missing grab of AccessExclusiveLock in DROP TABLE, ALTER/RENAME TABLE, etc, as noted by Hiroshi. Recommend 'make clean all' after pulling this update; I modified the Relation struct layout slightly. Will post further discussion to pghackers list shortly.	27 years ago

Bruce Momjian	4390b0bfbe	Add TEMP tables/indexes. Add COPY pfree(). Other cleanups.	27 years ago
Bruce Momjian	c91dbcc5c7	The following patch finishes primary key support. Previously, when ... a field was labelled as a primary key, the system automatically created a unique index on the field. This patch extends it so that the index has the indisprimary field set. You can pull a list of primary keys with the followiing select. SELECT pg_class.relname, pg_attribute.attname FROM pg_class, pg_attribute, pg_index WHERE pg_class.oid = pg_attribute.attrelid AND pg_class.oid = pg_index.indrelid AND pg_index.indkey[0] = pg_attribute.attnum AND pg_index.indisunique = 't'; There is nothing in this patch that modifies the template database to set the indisprimary attribute for system tables. Should they be changed or should we only be concerned with user tables? D'Arcy	27 years ago

Bruce Momjian	e0058b6172	Theses buffer leaks are caused by indexes that are kept open between ... calls. Outside a transaction, the backend detects them as buffer leaks; it sends a NOTICE, and frees them. This sometimes cause a segmentation fault (at least on Linux). These indexes are initialized on the first lo_read/lo_write/lo_tell call, and (normally) closed on a lo_close call. Thus the buffer leaks appear when lo direct access functions are used, and not with lo_import/lo_export functions (libpq version calls lo_close before ending the command, and the backend version uses another path). The included patches (against recent snapshot, and against 6.3.2) cause indexes to be closed on transaction end (that is on explicit 'END' statment, or on command termination outside trasaction blocks), thus preventing the buffer leaks while increasing performance inside transactions. Some (all?) 'classic' memory leaks are also removed. I hope it will be ok. --- Pascal ANDRE, graduated from Ecole Centrale Paris andre@via.ecp.fr	28 years ago
Bruce Momjian	6bd323c6b3	Remove un-needed braces around single statements.	28 years ago
Bruce Momjian	09baa3cc81	This patch... ... 1. Removes the unnecessary "#define AbcRegProcedure 123"'s from pg_proc.h. 2. Changes those #defines to use the names already defined in fmgr.h. 3. Forces the make of fmgr.h in backend/Makefile instead of having it made as a dependency in access/common/Makefile *hack*hack*hack* 4. Rearranged the #includes to a less helter-skelter arrangement, also changing <file.h> to "file.h" to signify a non-system header. 5. Removed "pg_proc.h" from files where its only purpose was for the #defines removed in item #1. 6. Added "fmgr.h" to each file changed for completeness sake. Turns out that #6 was not necessary for some files because fmgr.h was being included in a roundabout way SIX levels deep by the first include. "access/genam.h" ->"access/relscan.h" ->"utils/rel.h" ->"access/strat.h" ->"access/skey.h" ->"fmgr.h" So adding fmgr.h really didn't add anything to the compile, hopefully just made it clearer to the programmer.
